“I saw the koala on the mooring and at first I thought it was a stuffed toy,” Sean Hannam, a crew member on the boat, told local news.

Hannam and Sissons knew they couldn't just leave him there. He was obviously tired and stranded after swimming out there (koalas actually can swim, but not all that well) and was disoriented about to how to get back on dry land.

"He got to walk away gracefully," Hannam wrote about the koala on Facebook, under the pictures he posted of the rescue. And in response to the "good job" comments, he replied: "Just the conservationist in me."
